Know before you buy
The Lightweight option is designed for warmer climates or hot sleepers, featuring a lower fill weight for breathability. The All-Season option contains more down, providing extra loft and insulation for those who prefer a heavier, warmer feel throughout the year.
The duvet features baffle box construction, which uses internal fabric walls to create individual compartments. This design keeps the down evenly distributed across the entire insert, preventing cold spots and clumping.
Yes, the down is Responsible Down Standard (RDS) certified. This ensures that the materials are sourced from animals that have been treated humanely and protected from unnecessary harm.
While you could technically use it alone, it is designed to be paired with a duvet cover. Using a cover protects the organic cotton shell from stains and wear, and makes it much easier to keep your bedding clean.
This certification means the duvet has been tested and verified to be free from harmful levels of over 100 substances known to be toxic or hazardous to human health. It ensures the product is safe for you and your family.
The Full/Queen size measures 90” x 90”, while the King/Cal King size measures 106” x 90”. We recommend measuring your current duvet cover or mattress dimensions to ensure the insert provides the drape and coverage you prefer.
